I’ve been dealing with random freezes/crashes on my PC for quite a while and I’m trying to figure out which component is actually causing the problem.
My hardware
CPU: AMD Ryzen 7 5700X3D
GPU: AMD Radeon RX 7900 XT
Motherboard: MSI B550M PRO-VDH (MS-7C95)
RAM: 32 GB DDR4 (2×16 GB), currently running at 3600 MHz with XMP
SSD: 2 TB Kingston NVMe
PSU: 850 W
OS: Windows 11
What happens
The PC randomly freezes, especially while gaming, but it can also happen while using Chrome or switching between browser tabs.
The typical freeze looks like this:
The screen freezes.
Initially, I can still move the mouse.
After around 10 seconds, the mouse also stops responding.
Sometimes the audio continues for a short time.
Eventually the whole system becomes completely unresponsive and I have to force the PC to shut down.
Sometimes the PC instead reboots by itself.
With OBS running (streaming/recording), it used to freeze after roughly 25 minutes. I then tested the game without OBS running, and it still froze, so OBS is not required to reproduce the problem.
Windows errors
The main error I’m getting is:
LiveKernelEvent 141
I’ve also had other LiveKernelEvent errors such as:
141
a1000001 (AMD_WATCHDOG-Dump)
a2000002
Windows created watchdog dumps, including:
WATCHDOG-20260902-2240.dmp
I previously looked at another watchdog dump and found references to:
dxgkrnl.sys
amdxe.sys
amdkmdag.sys
amdfendr.sys
amdsafd.sys
So the crash seems to involve the Windows/AMD graphics watchdog path, but I don't know if that necessarily means the GPU itself is defective.
I have also had older WHEA-Logger Event ID 18 errors reporting:
Machine Check Exception → Cache Hierarchy Error → Processor Core
So I’m also wondering whether the CPU, memory controller, motherboard or power delivery could be involved.
Things I have already tried
I don't want to keep repeating the same tests because I've already done quite a lot of troubleshooting.
Stress tests
I have tested:
CPU stress test → ~1 hour, no errors
RAM/memory stress test → ~1 hour, no errors
Power test → ~1 hour, no errors
Linpack → ~1 hour, no errors
GPU stress test → ~1 hour, no errors
Temperatures were also reasonable. The CPU reached the mid/high 80°C range under heavy testing, which is still within the Ryzen 7 5700X3D's limits.
BIOS
I updated the motherboard BIOS to the latest version.
That did not solve the problem.
I also checked PBO and Curve Optimizer. There is no manual CPU overclock or undervolt active.
RAM
I have also tested the system with XMP disabled, but the freezes still occurred.
Currently the RAM is running at:
DDR4-3600
FCLK 1800 MHz
MCLK 1800 MHz
1.36 V
timings 18-22-22-39
AMD GPU drivers
I suspected the AMD driver might be involved.
I used DDU in Safe Mode to completely remove the AMD graphics driver and then installed an older Adrenalin version.
With Adrenalin 26.8.1, Star Wars Zero Company froze after roughly 25 minutes.
I then clean-installed Adrenalin 25.4.1.
With 25.4.1, the game lasted around 60 minutes before freezing again.
So the older driver seems to improve the situation significantly, but it does not actually fix the problem.
What would you investigate next to identify the defective component rather than just applying random workarounds?
Also, if anyone with an RX 7900 XT has experienced freezes together with LiveKernelEvent 141 / AMD watchdog errors, I'd be very interested to hear what ultimately solved it.
